This is simultaneously due to the relative tracta bility of 2d CFTs and the world sheet theory on AdS$_3$ backgrounds. Despi te this\, when compared to their higher dimensional counterparts\, little effort has been made to construct AdS$_3$ string vacua. I will discuss an ongoing program to fill this gap.\n\nThere exists a rich variety of superc onformal algebras in 2d\, with distinct options even for a fixed number o f supercharges. This makes the problem of classifying holographic duals to CFTs realising these both interesting and broad. I will discuss how one m ay systematically realise the various algebras in supergravity\, and make use of G-structure techniques to find new classes of solutions in 10 and 1 1 dimensions. Particular emphasis will be given to a class of solutions in massive IIA preserving small ${\\cal N}=(4\,0)$ supersymmetry\, for which there is a concrete proposal for dual CFTs.\n LOCATION:https://researchseminars.org/talk/EGSS/13/ END:VEVENT END:VCALENDAR
